Description

Technical Field

[0001] The invention relates to an anti-counterfeiting technology product, in particular to a novel double-layer anti-counterfeiting label with a bottom and a preparation method thereof. Background Art

[0002] In the current market environment, anti-counterfeiting technology is essential to protecting consumer rights, maintaining brand reputation and promoting fair competition. As a key tool for distinguishing the authenticity of goods, the design and functionality of anti-counterfeiting labels directly affect product safety and market order. With the development of technology, anti-counterfeiting labels have evolved from a single identification function to a multifunctional one, including two main types: clear code and hidden code.

[0003] Clear code labels are mainly used for operations such as querying commodity logistics information and inventory entry. Such labels are usually printed with basic information such as the serial number, batch number, and production date of the commodity. Consumers and merchants can easily obtain the logistics dynamics and inventory information of the commodity by scanning the QR code or barcode on the label, thereby ensuring the full traceability of the commodity from production to sales.

[0004] The secret code label focuses on information verification and the issuance of marketing red envelopes. Through a specific verification system or APP, consumers can verify the authenticity of the product and obtain marketing red envelopes and other benefits provided by the brand. This design not only enhances consumers' confidence in purchasing authentic products, but also promotes interaction and loyalty building between brands and consumers.

[0005] However, criminals in the market take advantage of certain characteristics of anti-counterfeiting labels to counterfeit high-value products. They take advantage of the fact that the glue on the label will become less sticky under high temperature conditions, so they can remove the sealed anti-counterfeiting label by heating, replace the product in the package, and then re-label it for sale. This behavior seriously damages the rights and interests of consumers and has a negative impact on brand reputation and market order.

[0006] In order to meet this challenge, some manufacturers have developed fragile paper labels. This type of label uses fragile paper material as the base material and is made by compounding it with other materials. Fragile paper labels are prone to breakage when subjected to external forces, thus preventing criminals from removing the labels by heating and other means to forge products. However, fragile paper labels also have some limitations. When fragile paper is used alone as a base material, its fragility is good; but when compounded with other materials, the fragility of fragile paper will be affected by the composite material. Only when it is peeled off from the composite material can its fragility be fully demonstrated. This peeling property is uncontrollable, resulting in uncontrollable fragility.

[0007] In view of the current market demand, there is an urgent need for an anti-counterfeiting label with controllable fragility, anti-transfer and anti-reuse. Summary of the invention

[0008] In order to solve the technical problems existing in the background technology, the present invention provides a novel double-layer anti-counterfeiting label with a bottom, which has both clear code and secret code information, and the label cannot be transferred or reused.

[0009] The technical solution adopted by the present invention to solve its technical problem is: A novel double-layer anti-counterfeiting label with a bottom, comprising a surface material layer and a fragile anti-tear layer arranged in sequence from top to bottom, wherein: Part of the surface material layer has holes, and part of the fragile anti-tear layer can be observed from the hole area; The non-perforated area of ​​the surface material layer is compounded with the fragile anti-peeling layer through a one-time peeling material, and the one-time peeling material is no longer sticky after peeling; The surface material layer and the fragile anti-tear layer jointly carry clear code information, and the composite area of ​​the surface material layer and the fragile anti-tear layer is printed with secret code information, which cannot be observed through the surface material layer.

[0010] Furthermore, the plain code information includes plain code holographic image information and plain code digital information.

[0011] Furthermore, the plain digital information includes one or more combinations of QR codes, bar codes, numbers, letters, and characters.

[0012] Furthermore, the cipher information includes cipher holographic information and cipher digital information, and the cipher digital information is correlated with the plaintext digital information.

[0013] Furthermore, the fragile anti-revealing layer is a fragile paper layer.

[0014] Furthermore, a self-adhesive layer and a silicone oil paper layer are sequentially arranged below the fragile anti-tear layer.

[0015] A method for preparing a novel double-layer anti-counterfeiting label with a bottom, comprising the following steps: S1. Preparation of a holographic embossed plate with a clear holographic image and text information and a holographic embossed plate with a coded holographic image and text information, and designing a flower knife and a flower knife; S2. Imprinting the holographic information of the holographic embossing plate onto a plastic film coated with an embossing coating, and printing a water-washable ink in an area where an aluminum layer is not required, then aluminizing and washing away the aluminum layer on the water-washable ink layer, applying isolation white ink and drying the material after peeling off once; S3. Imprinting the coded holographic information of the coded holographic embossed plate onto another plastic film coated with embossed coating, printing water-washable ink in the area where the aluminum layer is not required, then aluminum-plating and washing away the aluminum layer on the water-washable ink layer to form a transparent area, coating with composite glue, and laminating with the plastic film coated with the one-time peeling material in step S2, and after laminating, coating glue on the coded holographic embossed surface and laminating with silicone oil paper to obtain a surface material layer plastic film; S4. Printing secret digital information on fragile paper stickers; S5. Use a pair of pattern knives to die-cut holes in the surface material layer plastic film obtained in step S3, and after die-cutting, the continuous surface material layer plastic film is positioned and composited with the fragile paper sticker in step S4, so that the secret digital information printed on the fragile paper is invisible; S6. Printing clear digital information on the surface material layer and the fragile paper exposed through the surface material layer; S7. Associating the plain digital information with the coded digital information on the fragile paper; S8. Use the second pattern knife to die-cut the material obtained in step S6, and discard the part other than the new double-layer anti-counterfeiting label with a bottom.

[0016] Furthermore, the shape of the first pattern knife is the same as the shape of the opening area, and the shape of the second pattern knife is the same as the shape of the anti-counterfeiting label.

[0017] Beneficial effects of the present invention: (1) The plain digital information is printed on the surface material layer and on the fragile paper that is exposed through the surface material layer. When the surface material layer is peeled off, the plain digital information will be destroyed, and the plain digital information cannot be completely peeled off and copied.

[0018] (2) There is an opening area on the surface material layer. After being compounded with the fragile anti-tear layer, a part of the fragile anti-tear layer is directly exposed to the outside without the compounded area. The fragile paper of the fragile anti-tear layer in the opening area is an independent layer of material, and no other film material is compounded with the fragile paper. Therefore, the double-layer anti-counterfeiting label with a bottom has both double-layer information, namely the clear digital information and the coded digital information, and the characteristic that the fragile paper is easy to break when peeled off, giving the double-layer anti-counterfeiting label with a bottom the characteristic that it cannot be peeled off and reused.

[0019] (3) Paste the new double-layer anti-counterfeiting label on the packaging. Use a mobile phone to scan the plain digital information, and then use your fingers to peel off the surface material layer. At the same time, the plain digital information is destroyed and cannot be reused. The fragile anti-peel layer and the secret holographic molded layer are left on the surface of the packaging as the bottom material. The secret digital information can be observed and entered or scanned for verification and query.

[0020] (4) When the anti-counterfeiting label is removed by heating with hot air at 200 degrees Celsius, the fragile anti-tear layer under the opening area of ​​the surface material layer has no surface supporting material, and the fragile anti-tear layer is broken, so the anti-counterfeiting label cannot be completely removed, thereby achieving the effect of anti-counterfeiting, anti-tear and anti-reusage of the anti-counterfeiting label. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Figure 1 It is a structural schematic diagram of the present invention.

[0023] In the picture: 1. Surface material layer, 2. Fragile anti-tear layer, 3. Adhesive layer, 4. Silicone oil paper layer, 5. Clear code information, 6. Secret code information. DETAILED DESCRIPTION

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] A novel double-layer anti-counterfeiting label with a bottom includes a surface material layer 1, a fragile anti-tear layer 2, a self-adhesive layer 3 and a silicone paper layer 4 arranged in order from top to bottom. The surface material layer 1 is the outermost layer of the label and is a material with openings in some areas. A part of the fragile anti-tear layer 2 below can be seen from the opening area of ​​the surface material layer 1.

[0026] The surface material layer 1 and the fragile anti-tear layer 2 below are compounded together by a one-time peeling material. Once the one-time peeling material is peeled off, it is no longer sticky. The peeling force between the surface material layer 1 and the fragile anti-tear layer 2 is smaller than the peeling force between the fragile anti-tear layer 2 and the adhesive layer 3. The surface material layer 1 and the fragile anti-tear layer 2 carry clear code information 5 together, and the composite area of ​​the surface material layer 1 and the fragile anti-tear layer 2 is printed with secret code information 6, and the secret code information 6 cannot be observed through the surface material layer 1.

[0027] Since the surface material layer 1 and the fragile anti-tear layer 2 carry the plain code information 5 together, and the surface material layer 1 and the fragile anti-tear layer 2 use a disposable composite material, the characteristic of this material is that it is not sticky after being peeled off, and the peeled part cannot be repeatedly pasted on the fragile anti-tear layer 2. When the consumer scans the plain code information 5 and peels off the surface material layer 1 to verify the secret code information 6, the integrity of the plain code information 5 is destroyed, and the plain code information 5 cannot be reused, thereby ensuring the security of the data.

[0028] The fragile anti-tear layer 2 is located under the surface material layer 1, and the fracture strength of the fragile anti-tear layer 2 is much smaller than the peel strength of the anti-counterfeiting label. The surface material layer 1 and the fragile anti-tear layer 2 are compounded together. When the compound area of ​​the surface material layer 1 and the fragile anti-tear layer 2 is peeled up to the opening area, the fragile anti-tear layer 2 is directly subjected to force. The fracture strength of the fragile anti-tear layer 2 is much smaller than the peel strength of the anti-counterfeiting label. The fragile anti-tear layer 2 will first break due to a smaller external force, and the label cannot be completely peeled off, ensuring that the anti-counterfeiting label cannot be completely peeled off and reused.

[0029] The plain code information 5 includes holographic information and plain code digital information. The plain code digital information includes one or more combinations of two-dimensional codes, bar codes, numbers, letters, and characters.

[0030] The cipher information 6 includes cipher holographic information and cipher digital information. The cipher digital information and the plain digital information are correlated.

[0031] The anti-counterfeiting label is pasted on the package. After the surface material layer 1 is peeled off from the one-time peeling material, the secret code information on the fragile anti-peeling layer 2 can be viewed. The secret code holographic image information area and the secret code digital information area do not overlap each other.

[0032] A method for preparing a novel double-layer anti-counterfeiting label with a bottom, comprising the following steps: S1. Prepare a clear code holographic molded plate and a dark code holographic molded plate, design flower knife one and flower knife two, make flower knife one have the same shape as the opening area, flower knife two have the same shape as the anti-counterfeiting label, and flower knife two has a breakpoint connection in the opening area.

[0033] S2. Use a plastic film coated with molding paint as the molding substrate of the surface material layer, emboss the clear code holographic embossing plate onto the molding substrate of the surface material layer on a molding and gravure printing machine, and print water-washable ink in the area where the aluminum layer is not required, aluminum-plate the plastic film with the water-washable ink and wash off the aluminum layer on the water-washable ink layer; coat the plastic film after aluminum washing with isolation white ink, and coat the one-time peel-off material on the white ink for drying.

[0034] S3. Use a plastic film coated with molding coating as a coded holographic molding substrate, emboss the coded holographic image information of the coded holographic molding plate onto the coded holographic molding substrate on a molding and gravure printing machine, print water-washable ink in the area where the coded digital code needs to be displayed, aluminum-plate the coded holographic molding substrate and wash off the aluminum layer on the water-washable ink layer, apply composite glue, and composite it with the one-time peeling material of the plastic film in step S2, apply glue on the surface of the coded holographic molding substrate and composite it with silicone oil paper.

[0035] S4. Printing coded digital information on fragile paper stickers.

[0036] S5. Use a pair of pattern knives to die-cut the surface material layer plastic film after compounding in step S3. The discontinuous opening area and the continuous surface material layer plastic film are divided into two parts and rolled up separately. The opening area part is rolled up together with the silicone oil paper. The continuous die-cut surface material layer plastic film is positioned with the fragile paper sticker in compounding step S4, so that the secret code digital information is blocked by the surface material layer plastic film.

[0037] S6. Use a digital printing machine to print the plain digital information on the surface material layer and the fragile paper exposed through the surface material layer, so that part of the plain digital information is printed on the surface material layer and part of it is printed on the fragile paper.

[0038] S7. Associate the plaintext digital information with the coded digital information on the fragile paper.

[0039] S8. Use the second pattern knife to die-cut the material obtained in step S6, and discard the part other than the new double-layer anti-counterfeiting label with a bottom, to obtain a new double-layer anti-counterfeiting label with a bottom.

[0040] Example 1 A method for preparing a novel double-layer anti-counterfeiting label with a bottom, comprising the following steps: (1) Prepare a clear code holographic embossed plate and a concealed code holographic embossed plate, design a pattern knife 1 and a pattern knife 2, wherein the pattern knife 1 is used to die-cut the plastic film of the surface material layer so as to expose the opening area of ​​the fragile self-adhesive layer below, and the pattern knife 2 is used to die-cut the anti-counterfeiting label into individual labels and form breakpoint connections inside the label, especially on the fragile self-adhesive in the opening area.

[0041] (2) The holographic image information of the holographic embossing plate is embossed onto a 20-micron thick PET plastic film coated with embossing coating on an embossing gravure printing machine, and water-washable ink is printed online in the area where the aluminum layer is not required, the aluminum layer is vacuum-evaporated and the aluminum layer covering the water-washable ink layer is washed away, isolation white ink is applied, the material is peeled off once, and then dried.

[0042] (3) The coded holographic image information of the coded holographic embossing plate is embossed onto another 15 μm thick PET plastic film coated with embossing coating on a embossing gravure printing machine, and water-washable ink is printed in the area where the aluminum layer is not required, and then the aluminum layer is vacuum evaporated and the aluminum layer on the water-washable ink layer is washed away to form a transparent area, and composite glue is applied and composited with the plastic film coated with the one-time peeling material in step (2). After the composite, glue is applied to the coded holographic embossing substrate surface and silicone oil paper is composited to obtain a surface material layer plastic film.

[0043] (4) Printing secret digital information on the fragile paper sticker, the fragile paper sticker uses matte white 180g extra fragile paper.

[0044] (5) Use a pair of pattern knives to die-cut holes in the surface material layer plastic film obtained in step (3), and divide the surface material layer plastic film into two parts: an independent hole area and a die-cut surface material layer plastic film, and roll them up separately. The discontinuous hole area is rolled up with the silicone oil paper, and the glue surface of the die-cut surface material layer plastic film is positioned with the fragile paper in step (4) so ​​that the secret code digital information printed on the fragile paper is invisible, and the secret code digital information and the transparent image of the secret code holographic image of the surface material layer plastic film form a positional correspondence.

[0045] (6) Printing clear digital information on the surface material layer and on the fragile paper exposed through the surface material layer.

[0046] (7) Associating the plaintext digital information with the coded digital information on the brittle paper.

[0047] (8) Using a second pattern knife, the material obtained in step (6) is die-cut to make holes, and the part other than the new double-layer anti-counterfeiting label with a bottom is discarded.

[0048] When in use, after sticking the above-mentioned new double-layer anti-counterfeiting label with a bottom on the corrugated cardboard box, use fingernails to peel off and scrape from the edge of the label. The label is divided into two parts, the peeling part and the bottom part, from the one-time peeling material. The peeling part has an opening in the area where the fragile paper is not compounded, and the part below the secret holographic image information is the bottom part.
